How to troubleshoot a wireless connection issue

NOTE: Because each of these steps represents a possible solution to this issue, try connecting to the wireless network and view Web sites using the Internet Explorer® browser after completing each step.

NOTE: If the connection works in safe mode, the issue is likely caused by anti-virus or anti-spyware software. Configure the software properly per the manufacturer's instructions.

WARNING: If anti-virus or anti-spyware software has been removed or disabled to troubleshoot the issue, Sony recommends enabling or reinstalling it to prevent exposure to malicious software. Once the software is enabled or reinstalled, configure it properly per the manufacturer's instructions to allow the Internet or network connection to work correctly.

Check the WAN IP address of the router as per the manufacturer's instructions.

NOTE: If the router is not getting a WAN IP address, the issue is likely caused by a problem with ISP.

WARNING: There is a risk of data loss. If a router has been specifically configured (PPPoe, DSL, MAC address filtering, security, etc.), the settings will be removed by resetting the router and it will have to be reconfigured.

Reset the router and/or modem per the manufacturer's instructions.

If available, install a firmware update for the router and/or modem. Check the Web site of the manufacturer for updates and instructions.
